Alloy Steels

Carbon steel is a simple composition of Carbon and Iron. This type of steel roughly accounts for 90% of steel production. In order to obtain different characteristics, additional elements in small amounts are added to this alloy. High strength low alloy steel, for example, typically has 1.5% manganese and other elements to achieve the desired strength. Low alloy steel typically uses molybdenum, manganese, chromium, or nickel up to 10% by weight. Stainless steel contains a minimum of 11% chromium.

3003 Aluminum

3003 Aluminum is an alloy with good corrosion resistance and 1.2% manganese to give more tensile strength. It has excellent workability and weldability properties for aluminum alloys.  It is an alloy that is not heat treatable and can only develop strengthening from cold working. Some of the common uses for the alloy include drawing spinning, cooking utensils, kitchen equipment, storage tanks, chemical equipment, pressure vessels, refrigerator panels, gas lines, etc.

Ornamental Steel Display

Check out Tell Steel Inc.'s new Ornamental Steel display in Bay 1. The products and components look excellent on the stainless steel tubing and stainless steel rebar. Bob and Alberto did an excellent job building the display!

Shipwreck Salvage

The Palmyra Atoll and Kingman Reef were deemed Wildlife Refuges in the early 2000’s where a shipwreck had been damaging the ecosystem since the early 50’s. Curtin Martime and The US Fish and Wildlife just completed a mission to clean the shipwreck. The mission went flawlessly and now the salvaged metal will be recycled. Congratulations and Good Job to our local Long Beach citizens!

A 285 Grade C

A285 Grade C is an intermediate to low yield carbon steel. The primary uses for this metal are for vessels and boilers in the oil and gas industries. Due to its lower yield strength it is intended for boiler where moderate strength and good forming are required rather than in high pressurized vessels.  A 285 has a tensile strength of 55, to 75,000psi, yield strength of 30,000psi and an elongation of 27% in 2” and 23% minimum in 8”. Both forming and welding can be done on A285 Grade C using conventional methods. These plates are intended for fusion welded pressure vessels.

AH DH

AH36/DH 36 is a type of structural carbon steel that has been standardized by the American Bureau of Shipping. These steels have been optimized to be long-lived shipbuilding steels for use in shipbuilding, and are almost exclusively utilized in the Shipbuilding industry.  AH36/DH36 are higher strength ABS steels with a tensile strength of 70-90,000 psi, a yield strength of 51,000 psi and 17% minimum elongation in 8”, 20% minimum elongation in 2”. The material is intended for use in riveted, bolted or welded construction of bridges and buildings and for general structural purposes.
